Teleoceras is an extinct genus of grazing rhinoceros. It lived in North America and southwestern France during the Miocene epoch, which ended about 5.3 million years ago, through the early Pliocene epoch.

Teleoceras had much shorter legs than modern rhinos, and a barrel chest, making its build more like that of a hippopotamus than a modern rhino. Like the hippo, it was probably also semi-aquatic. Teleoceras had a single small nasal horn. It was a quite heavy animal, reaching 1.81 tons in weight.
